ORGANIZED LIFTING MECHANISM.

lily present invention pertains to litting means, and contemplates theprovision of an organized lifting mechanism of peculiar and advantageousconstruction, designed more especially for use as a lamp support in thehot air incubator constituting the subject of my contemporaryapplication, tiled February 19, 1925, Serial No. 10.356. (it which thisapplication is a division.

in the accompanying drawings. forming part of this application:

Figure 1 is a fragmentary sectional view of an incubator showing thein'iproved lamp supporting means in elevation and associated therewith.

Figure 9. a similar view showing the lamp construction with its supportin section.

Figure 3 is a side elevation of the incubator lamp and supporting meansthereol with the lamp lines in section.

Referring to the drawings in deta l the letter A indicates an incubatorof the type referred to B the heating flue, C the ventilating tlues bothof which are disposed in a casing l) and which are fully described in mysaid application, Serial No. 10.356.

Depending from the lower side walls oi the flue casing D are guide bars1 receiving sleeves 2 for the vertical slidable movement oi the sleevesthereon. The sleeves are provided with outwardly extending arms 3 havingright angled downturued ends s Passing through the lower end portionsoi" the guide bars 1 is a rock shaft 5 formed with a handle (3 at oneend for rocking the same for a purpose which will be presently apparent,and fixed to said rock shait at its ends are cams 7 of similarconstruction and adapted to engage the outwardly attending arms 3 of thesleeves tor raising and lowering a platform 3 which carries the lamptount 9 formed with a filling spout l0. and having secured thereon inspaced parallel relation with respect to each other a pair of bru'ners11 and 12 with the chimneys 1 3 and let therefor as clearly shown inFigure 3 of the drawings and which are adjustablv associated with thetines B and C. The platform 8 is supported in its lowermost position bya cross piece 15 and has provided wicks.

Divided and this application filed august on its ends the sleeves 2 asclearly shown in Figure 3 of the drawings.

Manitestly when the cams T are positioned as shown in Figures 2 and 3.the chimneys 13 and la: will be arranged with their upper ends in thelower ends of the tines i and C respectively, while when the swinginghandle 6 is manipulated to swii'ig the cams in the direction indicatedby the arrow in Bigure 1 the platform 8 will be permitted to gravitateuntil the tount rests on the bar 15 so that access may be readily gainedto the t'ount :tor filling the same with oil and access may he gainedalso to the burners for the adjustmentof their wiclis or the trim" mingof the wicks or for the removal thereot and the replacement of same withfresh litter any one of the operations above indicated. the platform isreadily restored to working position by swinging the aims 7 in theopposite direction through the iustrumentality of the handle 6 as willbe readily apparent.

It is thought from the foregoing description that the advantages andnovel teatnres of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts. providedthat such changes tall within the scope oi the appended claim.

lVh-at 1 claim is:

In combination. vertical spaced guide bars in parallelism, a cross barinterposed between and connecting the lower ends or said vertical bars,a vertical movable platform disposed between said guide bars and adaptedin one position to be supported by said cross liar said platform havingits ends vertical sleeves mo able on said guide bars, and said sleeveshaving outwardly and downwardly extending arms. a rock shaft journuledin said vertical guide bars. b low said cross bar and havin a handle atone end. and verticallyulisposefl cams Fixed to said rock shaftalongside said sleeves and located between the sleev and the down wardlyextending portions of said arms.

In testimony whereof I allix my signature.
